 Military Sex Bot 

 A support Android for combat unit that helps carrying equipments, acting as medic, and mental support. And of course, including lust. Body parts are exchangable.  (exchange process is very easy, even front-line soldiers can do it without engineering knowledge.) 

 The looks, including A.I., can be order made to fit each unit's need. (But immitating real person is prohibited) 

 It is very popular among the front-line soldiers. Some unit even praised her as a lucky goddess. However, because of protest from SJW, the production was cancelled immediately.
